DEVICE FOR COOLiNG ROLLS OF ROLLING-MILLS.

' SPECIFICATION formingpart of Letters Patent No. 265,731, dated October 10, 1882,

Application filed May 3, 1882. (No model.)

To all whom it may concern:

Be it known that I, JAooB ALTMEYER, a resident ofBen wood, in the county of Marshall and State of l/Vest Virginia, have invented certain new and useful Improvements in Cooling tolls in Rolling-Mills; and I do hereby de' clare that the followingisa full, clear, and eX- act description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters ofreference marked thereon, which form a part of this specification.

The objects of my invention are, first, to prevent the rolls from getting" too hot during the operation of rolling the iron, thereby causing injury to their working-surfaces and necessitating a suspension of work until the rolls are sufliciently cool to be used; second, to reduce the temperature of the atmosphere about the rolls and to cool the floor or platformupon which the workmen stand, and to provide them with cool fresh air to aid them in withstanding the excessive heat attending the operation of rolling iron. These objects I attain by the application of air direct to the working-surfaces ot'the rolls, and to air-chambers under the floors,

- arranged with perforated covers, by means of a system of air-,conveyinp pipes, through which the air is forced by the aid of a suitable fan or blower.

The invention consists in combining with an air-receptacle a system of peculiarly-arranged pipes having air-discharge orifices, all as fully hereinafter described.

In the drawings, Figure 1 is a plan showing a train of rolls and the system of air-pipes and air-chambers in connection therewith. Fig. 2

is a front view of one set of rolls; Fig. 3, a trans- "erse section through the center of the rolls.

For convenience of reference the description will be confined to one set of rolls, it being understood that the system can be extended to embrace a series of trains of rolls placed, if desired, in different parts of the mill.

On the drawings like letters of reference refer to like parts.

The letter A designates the rolls; B, the housing.

0 (J are metallic'platt'orms, one on each side of the train of rolls. These platforms are provided with perforations through the top, similar to a pavementgrating.

D is a box or airchamber under the platform, made preferably of cast metal, the platform fitting on it and forming a lid for the same.

E E are large airservice pipes, running the entire length of the line of rolls and coni'iectcd with a suitable blower, M.

H H are small supply-pipes, leading from the large mains into the side of the housings of the rolls, and are then continued upward, preferably on the front of the housing, across the top of the same, to which it is attached by suitable fastenings.

G Gr arepcrt'orated pipes, running parallel with the rolls at the top and at the bottom of the rolls, on opposite sides of the same, and at a suitable distance from them, connected at each end to the supply-riser It in front of the housing. These pipes are made with a line of perlorations or air-slots (not shown) running the entire length of the rolls, and are so arranged with screw-thread connections at the ends that the pipes can be turned around sufficiently to bring the line of air holes or slots at any desired angle with the rolls.

[1 b are small branches or nozzles to direct the air on thejourual-bearings of the rolls.

0 c are branches connected with the pipe G to supply the air-boxes I) under theplatforms. e e are regulatirig-valves.

Where more than two rolls are used in one housing a line of perforated pipe can be introduced between the risers for each roll.

The advantage of having the entire space open under the platform is to allow of an equal distribution of the air through the perforated cover to the workmen, thus avoiding upward currents or streams of air, which would carry with them the dust and scale that accumulate about the rolls, which would be the case it the space were divided into small air-fines with a line ot'air-holes through the cover parallel with them.

The operation of the system of air-pipes is as follows: The air, being forced through the mains and the various branches by means of the blower, is directed onto the working-surfaces aud journal-bearings of the rolls and into the air-boXes under the floor in any desired quantity, serving to cool the rolls and reduce the temperature around them and supply the workmen with cool fresh air.

I do not wish to confine myself strictly to the special arrangement of the air-pipes herein shown, as it is obvious that their form and shape may be varied considerably to produce the results aimed at without materially affecting the principle involved.

lflavingdescribedmyinvention, whatlclaim and desire to secure by Letters Patent of the United States, is-

1. A system ofair-conducting tubes for cooling' rolls in rolling-mills, consisting substantially of a line of perforated air-pipes running parallel with each roll, adapted to discharge a stream of air upon their surface, a series of branch supply-pipes connecting the same with a service-pipe running" parallel with the train of rolls, and a fan or blower adapted to drive the air through the pipes, all combined and operated substantially as herein shown.

2. The combination, with the rolls A and housing B, of the perforated pipes Gr G, fitted with nozzles b b, riser k, supply-pipes H H, service-pipe E, and fan or blower M, substantially as herein shown, and for the purpose set forth.

In testimony that I claim the foregoing as my own I hereunto affix my signature in presence of two witnesses.
